The energy consumption cost of the back of emission reduction can't be ignored

" We often say energy-conserving emission reduction, but actually energy-conservation and emission reduction are body of a contradiction, emission reduction often consumes energy. A researcher does not set up relevant model and parameter to the energy-conserving problem in emissio n reduction so far. " In the first stage of theme has been recently " Several scientific questions of energy-conserving mechanism in the industrial emission reduction of t he course " Fragrant Hills meetings scientific at, say one of meeting executive chairman, Professor of Nanjing polytechnical university XiaoHua Lu, realize valid energy-conservation in the industrial emission reduction of the course, it is to solve the energy of our country and " key " to the environmental problem .

The intersection of our country and " the eleven 5 " Plan to propose the clear index in reducing to ten thousand yuan GDP energy consumption, but to the emission reduction index, only propose the chemical oxygen demand (COD) And the reduction of total amount of sulfur dioxide discharge. " Because energy consumption cost and energy-conserving mechanism behind reducing displacement have nev er been paid attention to and announced, cause the state basic policy to be difficult to implement. " Lu XiaoHua says.

" Energy-conservation can obtain the emission reduction result at the same time, but the simple emission reduction course will increase energy consumption. Two goal these uncertain until to. " One of the executive chairmans of the meeting, Feng Xiao, Professor of Xi'an Communications University, think, energy-conserving emission reduction can be reconstructed, integrated, optimizes and realizes from the source through the course, need to complement and managing and meeting the environmental demand with the end at the same time. " What we face are optimum problems of the overall situation of many goals of resources, the energy, environment, economic and social coordination, the settlement of this problem depends on basic theory and method of the system engineering of the co urse. "

Course industry is through chemistry, physics or bio-transformation of the material, make new physical product, involve industrial fields such as chemical industry, petrochemical industry, energy, metallurgy, medicine, food, building materials, nuclear technology, biotechnology,etc..

It is reported, GDP that the course industry of our country produced has already exceeded 1/6 of the total amount, but energy consumption has exceeded 50% of the total amount; Meanwhile, this industrial field is a heavy polluter even more, the pollutant that various course industry in our country produce is various in style, complexity and energy consumption level dealt with differ greatly, the organic poisonous substance of difficult degradation such as the extremely low density, though COD high to poison extremely dark, punish energy consumption to be extremely high.

The expert participating in the conference points out, the centralized sewage handling which most urban industrial parks adopt at present definitely, actually mix sewages of different density, then separate the pollutant, have violated the scientific principle. Course industrial the intersection of emission reduction and route store variety, complexity in, pollute the energy consumption with emission reduction, shift, shift each other. So, consider emission reduction in process of production and want many kinds of methods to make up optimi zing, realize the step of resources is utilized; Terminal manage, want according to toxic the intersection of alternative and removal pollutant.

At present, because it is quantitative to lack both at home and abroad and describe the energy consumption data o f demand of different pollutant of emission reduction, cause, get science, reasonable, quantitative emission reduction index out of to different pollutant while being difficult, also difficult in order to really comment on the result of industry's energy-conserving emission redu ction of the course quantitatively, and provide the scientific solution. The expert thinks, this has brought great difficulty to final implementation of emission reduction.

On emission reduction of course industry, the domestic and foreign researcher reduces and dispels green chemistry or clean production of pollut ion and carries on research from source mainly, have already made a large number of achievements. " The green ' no emission ' of chemistry or clean production that is pursued both at home and abroad at present, while realizing the effective utilization of resources, reducing pollution, have often neglected the high energy consumption cost that it consumes. " Lu XiaoHua says, brings and pollutes and accumulates the national conditions of the total amount high to the industria l development of course of our country, the energy-conserving question in emission reduction is particularly outstanding. Existing research results consider supplies weighing apparatus charge and energy weighing apparatus a re calculated only at present, fail to make to opening system, complicated material, extreme condition quantitatively and describe, so can't comment on the result of industry's energy-conserving emission reduction of the course truly.

Energy-conserving emission reduction has already received the extensive concern of the whole world, the energy-conserving question to course industry, utilize concept to have efficiency let the intersection of energy and the intersection of step and us e to the maximum extent mainly. The conferee thinks, carry on coupling of course industry and new material and new energy industry, employ the chemical thermodynamics principle, combine the analytical method of the whole lifespan, set up the systematized model of energy-conserving emission reduction and new energy industry of ever y highly energy-consuming course industry, carry on science, objective, quantitative appraisal, can control energy-conserving potentiality and mechanism to study and offer the scientific criterion for the pollutant that the course of our country is complicated and changeable in industry.

" It is extremely urgent to set up and comment on the scientific standard of energy-conserving emission reduction of the course. " The meeting specially invites expert's East China University of Science and Technology academician Hu Ying to say. (news from Beijing on December 17)
